Cavernous Angioma of the Corpus Callosum Mimicking an Astrocytic Tumor : Case Report

概要

論文の詳細を見る
A 40-year-old female presented with a mass at the genu of corpus callosum manifesting as vertiginous sensation persisting for a couple of months. The preoperative diagnosis based on neuroimaging was astrocytic tumor, probably an oligodendroglioma. The mass was totally excised through a left interhemispheric approach without postoperative neurological deficits. Histological examination of the mass revealed only vascular components with tiny hemorrhage, compatible with cavernous angioma. Cavernous angioma at the genu of corpus callosum is very rare, and definitive diagnosis can be achieved only through surgery. Surgical intervention should be considered before starting radiotherapy without histological confirmation.
